Scientific Purpose/Goals: Obtain quasi-synoptic information on the suspended-sediment transport system within the South Texas OCS by obtaining samples of the water column for analyses of sediment texture and concentration, sediment mineralogy and trace metals, water chemistry, and coccoliths to establish temporal variability patterns; obtaining vertical transmittance-temperature profiles to establish regional turbidity patterns; and casting drift bottles to measure surface currents during the cruise period.

Summary of Activity and Data Gathered: This cruise was the last of 6 scheduled monitoring cruises to evaluate the temporal and spatial variability of turbidity patterns within the south Texas OCS region. The cruises were conducted between November 1975 and May 1977. Stations: 26; Vertical transmittance-temperature profiles: 26; Water samples: 78; Drift bottles: 335.
